Abstract

An energy harvesting display module is disclosed. The module includes a base substrate having a plurality of sub-pixels arranged in a substantially regular sub-pixel pattern. The subpixels are dispersed along the base substrate with subpixel separating areas between individual subpixels. The module further includes a top substrate disposed opposite and above the bottom substrate, and a photovoltaic region disposed between the bottom substrate and the top substrate within the sub-pixel spacing region.

Description

Integrated energy collection display module
Background
Conventional displays, such as those used in cycle computers, smart phones, smart watches, GPS navigation devices, fitness trackers, and the like, utilize a display module to provide a user interface to a user of the electronic device. These electronic devices may or may not employ a touch screen. In the case where no touch screen is provided, buttons and other user input devices are used to receive user input. Battery life is important for these devices because stopping the wearable device for recharging is annoying to the user. Some attempts have been made to equip smart watches with a translucent solar panel, such as by using a separate solar cell positioned on top of (or above) the display of the watch. However, the presence of such solar cell covers reduces the visibility of the display module. Thus, there is a need for an integrated energy harvesting display module that harvests solar energy without substantially obscuring its display.

Detailed Description
The following text sets forth a detailed description of numerous different embodiments. However, it is to be understood that the detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Many alternative embodiments may be implemented in view of the teachings and disclosure herein.
It will be understood that unless a term is used in this patent application using a sentence "as used herein, the term" is hereby defined to mean … … "or a similar sentence to be expressly defined, it is not intended that the term be limited in meaning, either explicitly or implicitly, beyond its plain or ordinary meaning, and such term should not be interpreted as being limited in scope based on any statement made in any section of this patent application.
A single pixel on a color sub-pixellated display is made up of several primary colors, typically three color elements-either ordered as cyan-red (BGR) or as red-green-blue (RGB) on various displays. Some displays have more than three primary colors, which are commonly referred to as multiprimary colors, such as a combination of red, green, blue and yellow (RGBY), or a combination of red, green, blue and white (RGBW), or even a combination of red, green, blue, yellow and cyan (RGBYC).
These pixel components (sometimes referred to as sub-pixels) appear as a single color to the human eye because they are obscured by optics and spatially integrated by nerve cells in the eye. However, the assembly is easily visible when viewed with small magnifying glass (such as a small magnifying glass). Above a certain resolution threshold, the color in the sub-pixel is not visible, but the relative intensities of the components shift the apparent position or orientation of the line.
Fig. 1A is a plan view of a mobile electronic device (in this embodiment, a wristwatch 10) according to one or more embodiments of the present disclosure. In various embodiments, the watch 10 is operable to provide user performance information and/or navigation functionality to a user of the watch 10.

The housing 102 may include a location determining component 142 located within the housing. For example, the location determination component 142 may include an antenna 111 having a ground plane. The ground plane may be formed by coupling a printed circuit board and/or a conductive cage to the antenna 111. The antenna 111 and the ground plane may be coupled using solder, a connection element, or a combination thereof.
The location determination component 142 may be a GPS receiver configured to provide geographic location information of the watch. The location determination component 142 may be, for example, a GPS receiver, such as
Figure BDA0004113298150000051
Those provided in various products of (a). In general, GPS is a satellite-based radio navigation system capable of determining continuous position, velocity, time and direction information. Multiple users may utilize GPS simultaneously. The GPS includes a plurality of GPS satellites that orbit the earth. Based on these orbits, GPS satellites can relay their locations to GPS receivers. For example, upon receiving a GPS signal (e.g., a radio signal) from a GPS satellite, the watch disclosed herein may determine the location of the satellite. The watch may continuously scan for GPS signals until it has acquired several (e.g., at least three) different GPS satellite signals. The watch may employ geometric triangulation, for example, wherein the watch uses known GPS satellite positions to determine the position of the watch relative to the GPS satellites. The geographical location information and/or the rate information may be updated for the watch, e.g., continuously in real-time.
The location determination component 142 may also be configured to provide various other location determination functionality. For purposes of discussion herein, the location determination functionality may be related to a variety of different navigation techniques and other techniques that may be supported by "knowing" one or more locations. For example, location determination functionality may be used to provide position/location information, timing information, speed information, and various other navigation-related data. Thus, the location determination component 142 may be configured in various ways to perform various functions. For example, the location determination component 142 may be configured for outdoor navigation, vehicle navigation, air navigation (e.g., for aircraft, helicopters), maritime navigation, personal use (e.g., as part of fitness related equipment), etc. Accordingly, the location determination component 142 can include various devices that determine location using one or more of the techniques described previously.
The location determination component 142 can, for example, use signal data received via a GPS receiver in combination with map data stored in memory to generate navigation instructions (e.g., direction-by-direction instructions to an input destination or point of interest), show a current location on a map, and so forth. The location determination component 142 can include one or more antennas 111 that receive signal data and perform other communications, such as communications via one or more networks. The location determination component 142 can also provide other positioning functionality such as determining average speed, calculating time of arrival, and the like.
The location determination component 142 can include one or more processors, controllers, and/or other computing devices as well as memory 108, the memory 108 for example for storing information accessed and/or generated by the processors or other computing devices. The processor may be electrically coupled to the printed circuit board and operable to process the position determination signal received by the antenna 111. The location determination component 142 (e.g., antenna 111) is configured to receive a position determination signal (such as a GPS signal from a GPS satellite) to determine the current geographic location of the watch. The location determination component 142 may also be configured to calculate a route to a desired location, provide instructions (e.g., directions) to navigate to the desired location, display maps and other information on a display, and perform other functions (such as, but not limited to, those described herein).
The memory may store mapping data and routing that is used or generated by the location determination component 142. The memory may be integral to the location determination component 142, a separate memory, or a combination of both. For example, the memory 108 may include a removable non-volatile memory card, such as a Transflash card. Memory is an example of a device-readable storage medium that provides storage functionality for storing various data associated with the operation of the watch 10, such as the software programs and code segments mentioned above, or other data that instructs the processor and other elements of the watch 10 to perform the techniques described herein.

The antenna 111 may be configured to receive and/or transmit signals (such as GPS signals), for example. Antenna 111 may be any antenna capable of receiving wireless signals from a remote source, including directional antennas and omni-directional antennas. Antenna 111 may comprise any type of antenna in which the length of the ground plane affects the efficiency of the antenna. In accordance with one or more embodiments of the present disclosure, antenna 111 is an omni-directional antenna with a ground plane. An omni-directional antenna may receive and/or transmit on two orthogonal polarizations depending on the direction. In other words, the omni-directional antenna has no dominant direction of reception and/or transmission. Examples of omni-directional antennas include, but are not limited to, inverted-F antennas (IFAs) and planar inverted-F antennas (PIFAs). In contrast to omni-directional antennas, directional antennas have a main lobe for reception and/or transmission over a sector of approximately 70 x 70 degrees in a direction away from the ground plane. Examples of directional antennas include, but are not limited to, microstrip antennas and patch antennas.
According to one or more embodiments of the present disclosure, antenna 111 may be an embedded antenna. As used herein, an embedded antenna refers to an antenna that is located entirely within the device housing. For example, the antenna 111 may be located entirely within the housing 102. In some embodiments, the antenna 111 may be an external antenna, wherein all or a portion of the antenna 111 is exposed from the housing 102.
As discussed, the location determination component 142 includes an antenna 111. The antenna 111 may be associated with an antenna support assembly, for example, formed on and/or within the antenna support assembly. Alternatively, the antenna 111 may be located on the top or one or more sides of the antenna support assembly.

These values and/or information may be presented in the viewing area 104.
In an embodiment, the watch 10 includes a user interface storable in memory and executable by a processor. The user interface represents functionality that controls the display of information and data to a user of the watch 10 in the viewing area 104. In some implementations, the display module within the viewing area 104 may not be integrated into the smartwatch, but rather may be connected to the outside using Universal Serial Bus (USB), ethernet, serial connection, or the like. The user interface may provide functionality that allows a user to interact with one or more applications of the watch 10 by providing input via a touch screen and/or an I/O device. For example, the user interface may cause an Application Programming Interface (API) to be generated to expose to an application functionality that configures the application for display in the viewing area 104 or in combination with another display. In an embodiment, the API may further expose functionality that configures the application to allow a user to interact with the application by providing input via a touch screen and/or I/O device. The application may include software that may be stored in memory and executable by the processor for performing a particular operation or set of operations that supply functionality to the watch 10. Example applications may include fitness applications, exercise applications, health applications, diet applications, cellular phone applications, instant messaging applications, email applications, photo sharing applications, calendar applications, address book applications, and the like.
